The present case continues the series of anomia treatment studies with contextual priming (CP), being the second in-depth treatment study conducted for an individual suffering from semantically based anomia. Our aim was to acquire further evidence of the facilitation and interference effects of the CP treatment on semantic anomia. Based on the results of the study of , our hypothesis before the treatment was that our participant would show short-term interference and at most modest and short-term benefit from treatment. To acquire such evidence would not only be important for the choice of anomia treatment methods in individual patients, but would also prompt further development of the CP method. The CP technique used for our participant included cycles of repeating and naming items in three contextual conditions (semantic, phonological, and unrelated). As predicted, the overall improvement of naming was modest and short-term. Interestingly, the contextual condition that corresponded with the nature of our patient's underlying naming deficit (semantic) elicited immediate interference in the form of contextual naming errors, as well as short-term improvement of naming. Based on this and a recent study by , it appears that despite short-term positive effects, in its current form the CP treatment is not sufficient for those aphasics who have a semantic deficit underlying their anomia. The possible mechanism and directions for future research are discussed.
本病例延续了一系列使用情境启动（CP）治疗命名障碍的研究，是针对一名患有语义性命名障碍个体进行的第二项深入治疗研究。我们的目的是获取关于CP治疗对语义性命名障碍的促进和干扰效应的进一步证据。基于之前的研究结果，我们在治疗前的假设是，我们的参与者会表现出短期干扰，并且治疗带来的益处最多只是适度且短期的。获取此类证据不仅对个体患者命名障碍治疗方法的选择很重要，还会推动CP方法的进一步发展。用于我们参与者的CP技术包括在三种情境条件（语义、语音和无关）下重复和命名项目的循环。正如预测的那样，命名的总体改善是适度且短期的。有趣的是，与我们患者潜在命名缺陷（语义）性质相对应的情境条件引发了以情境命名错误形式出现的即时干扰，以及命名的短期改善。基于此以及最近的一项研究，似乎尽管有短期积极效果，但就目前形式而言，CP治疗对那些命名障碍背后存在语义缺陷的失语症患者并不足够。文中讨论了可能的机制和未来研究方向。
